Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full behavioral burden. It does disclose the output artifacts (hooks, hashtag clusters, content angles) and the target platforms, which is useful. However, it says nothing about whether this is a read or generation operation, cost/latency, or any auth constraints, leaving gaps for an unannotated tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence covering the transformation, output types, and target platforms with no filler. It leans on marketing phrasing ('viral hooks') but remains compact and readable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 2-parameter, 0-required, no-output-schema generation tool the description is mostly adequate: it conveys input intent and output shape. It omits any indication of whether parameters are optional, how results are structured, or behavioral caveats, so it is viable but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters (keywords, targetPlatforms) are already documented in the schema, including the enum values. The description restates 'high-intent search keywords' and lists the platforms, adding only minor emphasis. Baseline 3 is appropriate when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific transformation: high-intent search keywords are converted into social hooks, hashtags, and content angles. That verb+resource pairing is distinctive and an agent can tell it apart from pure keyword-research siblings. It stops short of naming any sibling or scoping boundaries, so it lands at 4 rather than 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'cross-channel translation' framing implies the usage context (you have search keywords and want social creative), but there is no explicit when-to-use statement, no prerequisites, and no routing to alternatives such as google_ads_get_keyword_research or google_search_console_discover_social_seo_opportunities. Usage must be inferred.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
